Investors holding xUSD or mHYPER in vaults on MorphoLabs or Euler Finance should consider withdrawing immediately. The Staked Stream USD (xUSD) chart shows a sharp 13.3% drop in the last 24 hours, indicating significant instability and potential de-pegging from its intended $1 value. The author warns of "max opacity finance" and poor risk-reward, suggesting a lack of transparency and high risk in these DeFi protocols.
